Baterie, které Vás posunou dál... a výš
For common people on the street, "a battery is a battery", they imagine it as a simple object that is either cheaper or more expensive, but that other differences are not so significant.
But in reality, it is totally the opposite.
Especially with massive solutions where, due to economy, high demands on performance, durability, stability and reliability are expected.
Investment in battery is a substantial part of the budget of such a project, and the consequences of inappropriate selection can also bring substantial losses.
So how do you choose battery cells that will bring you profitability, not loss?
There is only one solution: extensive long-term testing of cells and their larger assemblies in laboratory conditions, simulating various real-world applications.
The words "lithium battery cell" hide a wide range of manufacturing technologies and different chemical bases.
One particular type of a battery cell that is suitable for one type of application is generally unsuitable for another application. Not even if it bears the brand of renowned manufacturer.
This is where our battery laboratory comes into force. Careful detailed testing of many battery cell parameters of different constructions from different manufacturers is the ultimate answer to each project.
We even go touch lengths that we send a failed cell, either from lab testing or from daily service, for a detailed analysis to university labs.
Based on the analytical data collected over many years, we can identify the right battery for your solution. And we can bet our life that it is so.
Even the best battery cell carries the disadvantage of all lithium cells: the susceptibility of handling. This needs to be addressed by the control hardware, which constantly monitors the data on individual cells / parallel strings in the battery and, based on these data, manages their parameters.

And here's a bit more for those battery types that are more interesting:
Chemistry of articles
The most common cell chemistry currently includes LFP (lithium-iron phosphate), NMC (nickel-manganese-cobalt) and LTO (lithium-titanate). Each type of lithium cell chemistry has specific performance characteristics that predetermine it for a specific application - for example, LFP chemistry is the ideal solution for home battery storage due to its high security and lower performance parameters.
Shapes of the cells
The most common forms of cells are:
The shape of the cells has a major effect on the final design of the module (battery).
